Hello
For fun made a cube and saved out as .osg, then edited in Shaders for
fun. Seem to work but if light moves, using light[0] in shader the
object does not appear to update. Any ideas?

Use osgexp and 3ds Max(v8) all the time, most often with Delta3D, and
have no problems with repeating UV's.
Open your .osg file
Where it describes your 'textureUnit'{ Texture 2d{
Look for
wrap_s and wrap_t these should both be set to 'REPEAT'
osgEXP should handle this without
ok, a couple datapoints: the .osg format parser:
1) is case-sensitive
2) silently ignores anything is doesn't recognize.
Your example shows File when the actual keyword is file.

Still no luck getting a Shader to be called from a .osg file, but was
told that calling up a Shader file with
Shader {
File do.frag
Was advised might need certain Shader version such as 2.3 or above

Hello
Noticed in this discussion talk about Blender and .OSG
So just thought I'd mention these Blender Papers I did for the Delta 3D

Hello
After much trial and error got a glsl shader running from within an .osg
mesh file by using 'program'.
Wondering if it is possible to simply make a call for a shader file
(.cg..etc) from within the .osg mesh file, instead of having to place
the whole shader code into the file.
No
I still don't understand how a 2.3Mb (uncompressed) dae file plus
0.3Mb of
jpeg data ends up as a 20Mbyte ive file!

Don't know how you're going about getting it in to .ive, but doing
artwork in 3dsMax and exporting using osgexp I can give some information
you might find useful.

Still working on putting a shader into an .osg model file, not a full

texture combo. No Vertex code seemed to work or just do from in a Model

Quick questions
